The results of the diesel emission scandal have found, Matthias Mueller, VW’s CEO, had no knowledge about the installation of cheating software in its vehicles.

German newspaper, Bild am Sonntag, has reported citing a report by Jones Day, a law firm investigating VW’s diesel emission scandal, that the company’s CEO, Matthias Mueller, did not have knowledge about the diesel emissions cheating scandal.

Mueller only found about the emission cheating software on September 18, 2015 when U.S. regulators brought to the world’s notice about VW’s fake emission tests.

Mueller became the company’s CEO on September 25 and was tasked to with turning around the firm. He was earlier the Chief Executive of Porshe, VW’s sports car division.

When asked to respond to requests for comments, VW’s spokeswoman responded saying Volkswagen could not comment on an ongoing legal investigation.
